why do we fall back in daylight savings time

Each year, in the
hours of a Sunday morning in March, 60 minutes from the clock and the reappears each year in November! No, it's not a magic trick в it's Saving! Saving (or в," as it's known in many parts of the world) was created to make better use of the sunlight hours of the summer. By в " clocks forward an in, we move an of from the morning to the evening. On the first Sunday in, we в back" and rewind our clocks to return to Standard. But where did Saving come from? And how is it useful? The idea was first suggested in an essay by in 1784, and later proposed to British Parliament by Englishman William Willett 1907. However, it did not become a standard practice in the United States until 1966. Saving was originally instituted in the United States during World War I and World War II in order to take of longer hours and save energy for the war production. In the years after World War II, individual states and communities decided whether they wanted to continue observing Saving and when to do so.


This meant some cities were an behind others even though they were only separated by a few miles on a map. In order to minimize the confusion, passed the Uniform Act in 1966, which standardized the length of Saving for the country. Saving is most helpful to those who live farther from the equator, where hours are much longer in the summer than in the winter. In locations closer to the equator, hours and nighttime hours are nearly the same in length throughout the year. That's why many cities and countries do not participate in Saving. In the United States, there are only a few places that do not observe Saving, including parts of Arizona, Hawaii, Puerto Rico, the U. S. Virgin Islands and American Samoa. There are currently about 70 countries that participate in Saving, though not necessarily on the same schedule as the United States. who recognizes Saving and when can sound like a very complicated math word problem. In Europe, Saving runs from the last Sunday in March through the first Sunday in October.


In the southern, where the summer season begins in December, Saving is recognized from December through March. Kyrgyzstan and observe Saving year-round; countries do not observe Saving at all. Advocates in support of Saving suggest that in addition to reducing crime and automobile accidents, extended hours also improve energy by allowing people to use less energy to light their businesses and homes. studies argue the energy saved during Saving is offset by greater energy use during the darker and months. Myths, truths, and debates about switching the clocks The terms Бspring forwardБ and Бfall backБ are used to describe a practice of changing standard time with the intention ofб БsavingБ (as in, making better use of) natural light. During daylight savings time (DST), clocks are turned ahead one hour, so that the sun rises later in the morning and sets later in the evening. The change is reversed in autumn. Originally enacted in the United States as a wartime conservation effort, observance of DST became federal law in 1918. (To dispel a common myth: It was not enacted for farmersБin fact, most farmers fought for its repeal. ) While it was quickly repealed after the war ended, DST was observed nationally again during World War II. By 1966, some 100 million Americans were practicing some type of DST through their own local laws.


In 1966, Congress acted to end the confusion and establish one consistent nationwide pattern. The Uniform Time Act of 1966 stated that DST would begin on the last Sunday of April and end on the last Sunday of October. (Any area that wanted to be exempt from DST could do so by passing a local ordinance. ) By 2005, the Energy Policy Act established that DST begins each year on the second Sunday in March at 2:00am and that the changeover back to standard time (ST) occurs on the first Sunday in November at 2:00am. How much difference can an hour make? Opinions about the 60-minute swap tend to be passionate. For instance, proponents say that DST saves energy because in the spring and summer months, more people may be outside in the evening and not using energy (in the form of artificial light) at home.


Some simply relish long summer evenings full of outdoor barbecues, swims, and late sunsets. Opponents say that any energy savings due to using less artificial light have been offset by an increased use of air-conditioning over the past few decades. They also argue that the drawbacks of springing ahead include increased, lost productivity, and a rise in traffic accidents due to during the first few days after the spring time change. Sadly, those traffic accidents can even include cars and bus drivers hitting young students who are walking to their bus stops or standing at them during the dark, early morning hours in the late spring and early fall. Clearly, over the past century or so, the U. S. has had conflicting views about the usefulness of DST. Will DST be around forever? Only time will tell. Not sure how to maximize efficiency during DST? Here are some tips on.
